Abstract
Homoboroproline has been shown to be an efficient bifunctional catalyst for the aldol reaction of acetone with p-nitrobenzaldehyde by using in situ Lewis acid tuning of the boronic acid esterification with a diol. Herein, asymmetric syntheses of homologues of this catalyst are developed to compare their catalytic capability and chemical properties with homoboroproline, and to probe the effect that chain-length separation of the amino and boronate groups has on the intramolecular B–N coordination, as well as other cooperative interactions, to explain their widely differing catalytic properties.
